I will debug and fix your backend code fast
Javier Cabado
About this gig
Is your backend throwing errors and blocking your production?
I am a Full Stack Developer ready to step in, identify the problem, and fix it fast.
When a critical API fails or a database connection drops, every minute counts. I specialize in troubleshooting complex backend systems and ensuring your application runs smoothly. My goal is not just to patch the error, but to provide a clean, optimized, and sustainable solution that prevents future issues.
I work with modern stacks and can handle urgent debugging for APIs, server configurations, database queries, and integration failures. You will get a professional who understands both the backend architecture and the frontend impact, ensuring your users never notice the downtime.
What I offer:
- Fast response for urgent fixes
- Clean code refactoring after the fix
- Clear explanation of what caused the error and how I solved it
- Testing to ensure the bug is completely gone
- Do not let a backend error ruin your day. Send me a message with your error logs or a description of the issue, and I will tell you exactly how we can fix it right now.
- Let us get your app back online.

Soy desarrollador backend y estudiante de Ingeniería Informática, especializado en automatizaciones, APIs y microservicios. Mi enfoque no es solo escribir código, sino diseñar arquitecturas sólidas y escalables.
Tengo experiencia conectando herramientas (Notion, extracción de datos) usando Node.js y gestionando despliegues cloud (Render). Si buscas a un profesional que analice tu problema, proponga la arquitectura técnica más eficiente y te entregue un producto llave en mano listo para integrar, estoy a tu disposición.

FAQ
Do I need to message you before placing an order?
Yes, please! It is crucial that I review your code and the specific error first to ensure I can fix it within the delivery time and to avoid unnecessary cancellations.
Do you fix front-end or visual design issues?
No, this Gig is strictly for backend logic, algorithms, scripts, version control conflicts, and database connections. I focus on structural and logical problems, not HTML/CSS or UI changes.
What if my code requires a complete rewrite instead of just a bug fix?
This Gig is designed specifically for debugging and fixing existing code. If I review your files and see that your project needs a full architectural rewrite or a new feature from scratch, we can discuss a Custom Offer tailored to that scope.
